I was bored one night which is common for me, but I did some math on how many periods I got my whole life roughly anyway. You usually get a peroid once a month, 12 months in a year. So I started my period when I was 11 and now I'm 17 so I had roughly 85 periods. Idk just kinda cool to me I'm amused easily. If you want tell me how many you had I would love to hear.
